If youve been keeping up with the Zhengs youll already know about Plutarch the pirate parrot and the Lovely and Talented Mrs. Zheng. 3s Arduino enabled Pirate Pendant, but weve got one more project in the hopper this season a Christmas light wall inspired by runaway Netflix hit Stranger Things. Plus, you yes, YOU can tweet to this wall and your tweet will appear as a eerie sequence of glowing Christmas lights outside my house. Try it yourself Be nice, you bastids. Let There Be Lights. Head out into the wilds of Amazon Prime and youll find plenty of LED Christmas lights that might and we must stress might fit the requirements of this project. It pains me to buy a 13 part to fix a problem I might have forseen but when one considers that 13 is an average morning at Starbucks for some folks, the bad feels. Point against our crack research team was dismayed to find that most modern Christmas lights seem to be spaced between 4 and 6 apart, which simply will not do for an application where the letters are more widely distributed. Also, its highly unlikely that your garden variety Sunday church picnic Christmas lights are individually addressable. So in theeeeeeory we could buy a roll of Christmas lights, hack them apart with a Dremel and wire cutters and hope theyre what we need, or we could just make our own. DIY is ultimately more satisfying, so to the 3. D printer it is Filabot was kind enough to send me a free roll of PETG for review. This filament prints somewhere between clear and frosty white, depending on the thickness of the models outer walls. Its easy enough to whip up a few dozen hollow Christmas lights bulbs in Maya.

These bases screw into the bulbs and have enough empty space in the bottom to accommodate a cut down female header for plugging and unplugging. Organization is key to completing a project with so many little parts Theres not a lot of space on them for labeling with proper digits, so I hashmarked each base with silver Sharpie. This will help keep the colors in the proper sequence when I string up the lights. Recovering from Failure. Strap in, muggles. Its going to get technical for about a few paragraphs here. Around Christmastime last year I was working on a project where I was trying to read data from 6. This project ultimately cratered, and we shall refer to it in hushed tones as the Multiplexer Incident of Winter 2. Its mostly behind us now. Mostly. On the plus side, I learned an awful lot about multiplexers and cabling and bought a slew of electronics and more hookup wire than Ill ever use. We can apply those newly gotten smarts and parts to the Stranger Things wall. First off, for those uninitiated WTF is a multiplexer In this context, a multiplexer or mux, if ye be in the know is a doodad that reads many signals into a single channel, or distributes one signal to many destinations. This wonderfully written post at bildr will tell you how to read from this Sparkfun mux breakout, and writing to the mux requires only a couple of small modifications to the code. Well be writing to this mux to light up LEDs in a specific sequence. Of course you need a bunch of colored LEDs, also. You dont want to run an LED without a current limiting resistor down that path lies a wastebasket of fried electronics. Each mux can handle up to 9 volts, but thatll cook the LEDs right quick. Happily these colored LEDs can be handily divided up into two groups those with an operating range of 2. V, and those that run at 3. V. I put one 1. 86 ohm on the SIG pin feeding the 2. V LEDs and a 1. 19 ohm on the other mux running the 3. I told you it was going to get technical for a few paragraphs. We want these LEDs to be in a predictable Christmas light like order red, green, blue, orange, pink, purple, yellow, repeat, so theres some software mapping of mux pin to LED happening in the Arduino code. Higher voltage LEDs are on the mux labelled B. Building A Wall, Except Mexico Didnt Pay for It, I Did. The budget for this project works out to less than 1. D printer in the basement and your time has no value. Programming microcontrollers, navigating the Twitter API, and tying it all together with heat shrink and hope is easy. Building stable outdoor displays out of 24s and plywood Thats hard, man. Definitely out of my element here, especially since I dont have an easy way to make miter cuts in 24s. Confession during construction, a piece of plywood fell down and hit me in the neck. With enough screws and construction adhesive the whole thing should hold together for a couple of weeks and hopefully not fall over onto any pint sized stormtroopers. Heres the finished product hat tip to our local Sherwin Williams for the Coriander Powder color match of a laser printed Stranger Things screenshot. The wires strung between the Christmas lights are black nylon rope the actual wiring is done with hookup wire stapled to the back of the wall. I also added and and Zheng. A Z. You should probably follow me on Twitter if youre not doing so already, cause I tweet about cool Maker shizz ALL THE TIME. This dogs breakfast of electronics parts are jammed into a hopefully waterproof Ziploc storage container attached to the back of the wall. Its a mess back there with the breadboards and jumper wires, but should be good enough for a temporary installation. Note warning label on it to discourage tampering andor theft. Reading From Twitter. Oy. A detailed description of how to do this is beyond the scope of this post. Suffice it to say that Im using Tweepy, OAuth, and a poorly written Python script that you can download here. Be sure to swap out my placeholder authorization tokens with your own. In pseudocode, heres how this whole thing works loop. Internet. Of. Stranger. Things tweets from Twitter. HAPPY HALLOWEEN, JUSTICEFORBARB, etc. ASCII codeloop. send the ASCII over serial to the Arduino as bytesmap the incoming byte to a mux pinlight the appropriate LEDwait a little bit between letters. Presumably one of the chans or reddit will eventually catch wind of this project, so before we send any text to the Arduino it gets filtered against a text file of slurs and epithets I keep around for precisely this purpose. There are kids around, for fucks sake. An old laptop sits inside, shoving sanitized data into the Arduino through a 3. USB cable. Thats right, the tweets are coming from INSIDE THE HOUSE. Download the microcontroller code here for a sterling example of how not to program an Arduino. Tweet anything you like with the hashtag Internet. Of. Stranger. Things and itll wind up on the wall if your text gets past the filters. Ill be tweaking the code between now and Halloween to make it more responsive to input from Twitter, and if I can figure out an easy way to set up realtime video stream Ill do that too. Happy Halloween if I dont talk to you sooner.
